Description

Technical Field

[0002] New energy charging piles play a vital role. They are energy supply stations for new energy vehicles. They replenish electricity for vehicles through charging methods of different powers to meet the needs of daily travel and long-distance travel. Their extensive construction has promoted the development of the new energy vehicle industry, reduced consumers' concerns about buying cars, and promoted automobile manufacturers to increase investment. In terms of energy and environment, charging piles are conducive to optimizing the energy structure, helping energy conservation and emission reduction, reducing exhaust pollution, and improving air quality. At the same time, it can also promote the construction of smart grids, balance electricity supply and demand through "peak shaving and valley filling" and vehicle-to-grid technology, and improve grid stability and energy utilization efficiency. It has an indispensable position in the fields of transportation and energy.

[0003] Existing wiring hubs for new energy vehicle charging piles generally do not have storage devices for connecting wires. The connecting wires are directly placed on the ground or hung on hooks on the outside of the charging pile body. There are many hazards in not having a storage device for the connecting wires. Placing them directly on the ground or hanging them on hooks on the outside of the charging pile may cause tripping and other safety hazards, accelerate aging and damage of the connecting wires, affect electrical safety and service life, destroy the overall appearance and order, and interfere with normal space utilization. General storage devices are not convenient for recycling and cleaning the connecting wires, and for winding or stacking the stored connecting wires, it is easy for the insulation layer to crack or be squeezed and deformed due to stress concentration. If dirt adheres to the connecting wires, it may also corrode the connecting wires. In terms of heat dissipation, poor air circulation may lead to heat accumulation and accelerated aging.

[0042] Specifically, the transmission member includes two groups of connecting rods 633, and two connecting rods 633 form a group. The two connecting rods 633 in each group are connected by belts and pulleys. The four connecting rods 633 are rotatably installed on one side of the header 2 through connecting components. The other ends of the four connecting rods 633 are fixed with single-sided pulleys 637. The outer sides of the two single-sided pulleys 637 close to the charging pile body 1 are equipped with a transmission belt 636, and the outer sides of the two single-sided pulleys 637 away from the charging pile body 1 are equipped with another transmission belt 636.

Each threaded rod 63 drives the two meshing blocks 64 outside each threaded rod 63 to move toward the side away from each other through meshing. The meshing blocks 64 located on the outside of the same threaded rod 63 drive the inclined rod 65 rotatably connected thereto to move toward the side close to the threaded rod 63.

The restriction on the connecting wires 3 is released layer by layer in turn, and the connecting wires 3 are released layer by layer.

[0046] After charging is completed, when the connecting line 3 is being wound up, as the connecting line 3 is climbing, the circular shaft 561 close to the charging pile body 1 drives the meshing belt 635 to rotate through the circular gear 2 634, and the meshing belt 635 drives one of the connecting rods 633 close to the top of the header 2 to rotate through another circular gear 2 634, and one of the connecting rods 633 drives the other connecting rod 633 close to the top of the header 2 to rotate through the belt and the pulley, and the two connecting rods 633 close to the top of the header 2 drive the two transmission belts 636 to reverse, and the teeth on the inner side of the two transmission belts 636 pass through the two connecting rods 633 close to the header 2.

This can effectively extend the service life of the connecting wires 3, while improving safety and avoiding tripping of pedestrians and mutual friction between the connecting wires 3.

[0048] Specifically, a support assembly 7 is provided on the inner side of the support assembly 6, and the support assembly 7 is configured to drive the two vertical rods 72 to move toward each other by contracting the telescopic rod 73, thereby releasing the fixation of the connecting line 3, and to drive the two vertical rods 72 to move away from each other by extending the telescopic rod 73 to fix the connecting line 3; the support assembly 7 includes a bottom plate 71, which is fixed to the inner side of the collecting box 2 through a connecting component, and the bottom plate 71 is located at the bottom of all the support plates 1 61 and 2 62, and two vertical rods 72 are rotatably installed at both ends of the inner side of the bottom plate 71, and telescopic rods 73 are rotatably installed on the inner sides of the top ends of the two vertical rods 72.

[0049] In this embodiment, before charging, the charging gun 4 is moved out from the inner side of the charging pile body 1. At this time, the telescopic rod 73 contracts and drives the two vertical rods 72 to move toward the side where the two vertical rods 72 are close to each other, thereby releasing the restriction on the connecting wire 3. After charging is completed and the cables are recovered, when all the connecting wires 3 are collected back to their original positions, the telescopic rod 73 extends and drives the two vertical rods 72 to move toward the side where the two vertical rods 72 are away from each other, and cooperates with the support to restrict and fix the connecting wire 3 again.

[0050] Working principle: The initial state is as follows Figure 1-Figure 11 As shown, before using this device, the staff moves the car to the front of the device, and then moves the charging gun 4 out from the inner side of the charging pile body 1. At this time, the telescopic rod 73 contracts and drives the two vertical rods 72 to move toward the side where the two vertical rods 72 are close to each other, thereby releasing the restriction on the connecting line 3. Then, the charging gun 4 is moved to the charging port of the car and connected. The charging gun 4 drives the connecting line 3 to move. The connecting line 3 drives the two circular shafts 561 to rotate through the two extrusion cylinders 56. The two meshing blocks 64 on the outer side of each threaded rod 63 move toward the side where the two meshing blocks 64 are away from each other. The meshing blocks 64 on the outer side of the same threaded rod 63 drive the oblique rod 65 rotatably connected thereto to move toward the side close to the threaded rod 63. The oblique rod 65 drives the two cross rods 67 to move toward the side where the two cross rods 67 are away from each other, thereby releasing the restriction on the next layer of connecting lines 3. The restriction on the connecting lines 3 is released layer by layer in turn, and the connecting lines 3 are released layer by layer.

[0051] After charging is completed, the staff removes the charging gun 4 from the inner side of the car charging port, and then moves the charging gun 4 to the charging pile body 1 and inserts it. At this time, the motor 52 is started, and the motor 52 drives the circular shaft 561 connected to its output end to reverse, so that the bevel gear 2 55 on the outer side of the circular shaft 561 is driven by the bevel gear 1 54, the transmission rod 53, another bevel gear 1 54, and another bevel gear 2 55 in sequence, driving the other circular shaft 561 to rotate forward (such as Figure 6 and Fig. 9As shown), the two extrusion cylinders 56 drive the connecting line 3 to be retracted into the collecting box 2. When the connecting line 3 climbs, each threaded rod 63 drives the two meshing blocks 64 on the outside of each threaded rod 63 to move toward the side where the two meshing blocks 64 are close to each other through the meshing action. The meshing block 64 located on the outside of the same threaded rod 63 drives the inclined rod 65 rotatably connected thereto to move toward the side close to the threaded rod 63. The inclined rod 65 drives the two cross bars 67 to move toward the side where the two cross bars 67 are close to each other, and returns to the original position, thereby limiting the connection of the next layer while providing placement support for the placement of the climbing connecting line 3.
